Frequently asked
Is it suitable for sensitive skin?
Yes. The Oil-In-Serum 4-Solution was pharmaceutically developed for reactive skin — it soothes, restores, balances and supports the skin barrier without fragrance-heavy irritants. If your skin is easily triggered by weather changes or dryness, this is the routine it was made for.
How do I use the Oil-In-Serum 4-Solution?
After cleansing, warm 2–3 drops between your palms and press gently into the face and neck, morning and night. Follow with your usual moisturizer. On very dry days, add an extra drop to the driest areas.
When will I see results?
Many users feel calmer, more comfortable skin within the first days of use. Visible changes in dullness, tightness and hydration typically show over 2–4 weeks of consistent morning-and-night use. Results vary from person to person.
Can I use it under makeup or with other products?
Yes. The serum absorbs quickly and layers cleanly under moisturizer, sunscreen and makeup. If you use strong actives such as retinoids or exfoliating acids, introduce the serum gradually and watch how your skin responds.
